Authentication templates include:

* **Fixed Text**: "Your verification code is \<VERIFICATION\_CODE>."
* **Optional Security Disclaimer**: "For your security, do not share this code."
* **Optional Expiration Warning**: "This code expires in \<NUM\_MINUTES> minutes."
* **Buttons**: One-tap autofill, copy code, or no button for zero-tap.

**Types of Authentication Templates**

1. **One-Tap Autofill Authentication Templates**:

* **Default TTL**: 10 minutes for new templates, but can be set between 60 and 600 seconds.
* **TTL Importance**: Ensure TTL matches your code's expiration time to avoid sending unusable codes.
